FILE FOR RECEIVING LOOSE SHEETS, MAGAZINES. AND THE LIKE.

Application filed. November 29, 192 1. Serial No. 752,902, and inDenmark September 9, 1924.

the file. All such files, however, have the disadvantage that itisdi'flicult to insert the loose sheets or the like where they belong,becausethe string on which the sheetsare to be inserted isattachedto theback of the file, both at the top and at the bottom.

only one end of the said string is attached tothe' file, so that thesaid string can be passed over the holding members at thetop and at thebottom on the inside of the-back of the file, accordingly as the file isfilled the sheet, and then passing it over one of the. holding devicesat the top or at the bottomof the back, before the string is finallyattached to the file.

Moreover it is a distinguishing feature of this invention that the saidholding devices, which serve the purpose of keeping the string in place,are attached to two metal channel bars of such a shape that, directlyfrom the end of the file, they can be pushed over the back of the saidfile, round which they are then pressed together. The tension of thestrings will then keep the metal bars in position without special meansbeing required. As the two sides and the back of the file can he made ofa single piece of millboard or the like, an exceedingly cheap andconvenient make of such a file may be attained.

A constructional form of the invention is shown in the accompanyingdrawing in which- Fig. 1 is a file which is opened; and

Fig. 2 is a longitudinal section through one end of the back of thefile.

The file consists of a back a with two sides I) and c, which togetherwith the back a may be made of a single piece of millboard or the like.On the juncture between the back and The present invention consiststherein that the side-parts a crease d is pressed into the cover, sothat the sidescan easily be turned relatively to the 'back a.

To the top of the back a is secured a number of hooks e e and at thebottom on the back a there is secured a corresponding number of hooks f7, By means of a rivet g or the like a disc h ofinillboard or the likeis attached to the rear side 0 of the cover.

A stringlc has at oneen'd an'eye or a loop Z by which it is ho'oke'd onto the hook ge and then ltis passed over the hook f and back over thehook'e As shown' oni'the: drawing it may then be passed over theihook fewhich is the rearinost of the hooks e; finally it is fixed below thedisc h by being pressed in between thesaid disc and the side-part 0. Thefree surplus end of the string 70 maybe twisted around a cardm hangingfrom the disc h and may be unwound therefrom as the file is filled moreand more. In order=to prevent the card m fromunwinding, the free end ofthe string may be left han ing from the card; so thatit-can bepresseddoelow the disc 71. together with the part of the string lyingbetween the hook 6 and the card m. 7

When sheets are to be inserted into the file shown, the string 7c isfreed from the disc h and from those hooks e and f over which it ispassed, with the exception of the hook 6,. The first sheet is nowbrought into place in the file below the hook c and the string 70 isinserted into the sheet, whereafter it is passed over the hook A. If nomore sheets are to be inserted into the file, the string 70 may now bepassed over the hook e, and then over the hook e and finally be fixedbelow the disc h. It is also possible, however, to pass the stringdirectly from the hook f, to the hook e and then to fasten it beneaththe disc h.

As shown in Fig. 2 the books 6 are made in one piece with a channel bara, which from the end is pushed over the back of the file. The bar withthe hooks on it is stamped out of plate and bent into the form shown inFig. 2. The channel bars a protect the ends of the back from wear andgive the necessary stiffness to the back in a transverse direction.Moreover, the said bars give a handsome and strong appearance to theback of the file when seen from behind. The sides 7) and 0 of the file,which parts, when the file is shut, are at right angles to the back a,are conducive towards giving the necessary stiffness to the said back ina longitudinal di rection.

The file described can be made in different sizes according to the sizeand the quantity of the sheets it is intended for. One of the advantagesof this invention is that it is possible, without procuring particulartools, to make files of any dimensions, as the back and the side partsare made simply by cutting out millboard or the like, and thedifi'eronce, as far as the channel bars are concerned, only consists inthe varying length of the said bars.

The constructional form of the invention shown in the drawing may bevaried in many ways, and it may here be mentioned that the constructionof the holding devices a and f and also of the disc A, in each.individual case, may be varied according to the demands put to the file.The disc It may be arranged at any point of the file. Instead of usingthe above mentioned arrangement to prevent the card m from unwinding bypressing the tree end of the string below the disc it, any othersuitable arrangements may be used; for instance, as it is customary withother cards, it is possible to employ a slit 0 disposed in connectionwith the card, into which slit the string may be engaged.

I claim:

1. A file for receiving loose sheets, magazines and the like, on theinside back of which both at top and bottom are disposed channel bars,the length of these bars being equal to the breadth of the back and thespace between the flanges thereof equal to the thickness of said back,said bars provided with books. a string adapted to retain the papersplaced into the file, attached at one end to the one of said bars andarranged in a zigzag line between the hooks of said top and bottom bars,respectively and a disc or the like attached to the rear cover of saidfile and adapted to have the free end of said string engaged between itand the rear cover.

2. A file for receiving loose sheets, magazines and the like, on theinside back of which both at top and bottom are disposed channel bars,the length of these bars being equal to the breadth of the back and thespace between the flanges thereof equal to the thickness of said back,said bars provided with books made in one piece with said bars bystamping out the one flange and being bent of]? therefrom, a stringadapted to retain the papers placed into the file, attached at one endto the one 01" said bars and arranged in a zigzag line between the hooksof said top and bottom bars, respectively, and a disc or the likeattached to the rear cover of said file and adapted to have the free endOSCAR JOHAN CHRISTIAN RIIS.
